I was on a plane at the omaha airport when i looked out the window and saw this object. at first i thought it might be a hot air balloon in the shape of a black square, but then i thought to myself, "what on earth would a hot air balloon be doing floating over the airstrip of the omaha airport!? maybe this is blindingly obvious to you guys and you can debunk it easily. but i don't know what it is, so i thought i would share it. thanks, keith
